| 中文摘要: |
| 应用透射电镜技术观察了中国绿螂(Glaucomya chinensis)精子的超微结构。精子为典型的原生型,包括头部、中段和尾部三部分。头部由顶体和细胞核组成。顶体呈倒"V"字型。细胞核呈长圆柱形,没有核前窝,具有核后窝。中段由4个线粒体环绕中心粒而成。尾部细长,为典型的"9+2"结构。文中还讨论了双壳类精子形态结构的种属间差异。 |
| 英文摘要: |
| The ultrastructure of spermatozoon in Glaucomya chinensis was observed with transmission electron microscopy.The mature sperm is typical primitive type,including the head,middle piece and tail.The head consists of acrosome and nucleus,and the acrosome takes the shape of inverted"V".The elongated cylindrical nucleus has a posterior nuclear pocket but has no front nuclear pocket.Four large mitochondria and two centrioles make up the middle piece.The flagellum is slender and shows the typical"9 + 2 " microtubular structure.This article also discusses the morphological differences of sperm structure among lamellibranches species. |
